    I use the Rate Reminder control in my app, and I have been recently receiving the following stack traces. Seems to be affecting quite a fwe of my users (I use Crittercism for bug analytics).

    Are you aware of this error? 

    System.NullReferenceException - Object reference not set to an instance of an object

    Stack Trace
